UNITED STATES NORMAN E. HOUSER, OF LOUIS, MISSOURI v SYRINGE Application filed/August 2, 1929. Serial No. 383,040.

The present invention relates to an atomizer or spray, and contemplates a construction wherein a continuous'luke-warm' or hot sterile medicated spray may be obtained instantly when desired, the invention residing in the construction, combination and arrangement of parts as claimed. i

In the drawings forming part of this application like numerals of reference indicate 1 similar parts in the several views, and

wherein Figure 1 is a side elevation of the device.

Figure 2 is a plan View partly in section showing the heating element. Figure 3 is a sectional view on line of Figure 2.

Figure 4 is a vertical sectional view through the syringev Figure 5 is a plan view thereof partly in section.

Referring to the drawings inldetail, indicates a container-of any suitable construction adapted to receive a medicinal solution, and while the container may be constructed from-any suitable material and vary in de sign it is preferably of the design illus trated and formed of glass The container 10 is closed at its upper end by means of a cast- 4, ing 11 constituting a cover, preferably formed with a depending flange 12, while interposed between the casting and the cover 11 is a suitable gasket 13.. Depending from the flange 12 at diametricallyopposite points are supporting arms 14 arranged at opposite sides of the container and having their lower ends extended toward each other and connected with a suitable nut 15, which accommodates an adjustable bolt or screw 16 as A clearly illustrated in Figure '1. This screw J has one end received by a recess formed in the bottom of the container to assist in supporting the latter between the arms 14. g

p The casting or cover 11 is formed with a thickened portion which terminates to provide a socket 17 projecting from one side of the container 10 and adapted to receive a heating device indicated generally at 18, and which has associated therewith a water supply pipe 19. The thickened portion of the casting is also formed with a vertical bore to receive the adjacent end of a hollow tube 20 which depends into the container 10 and terminating a slight distance from the bottom thereof, and through which tube the medicinal solution is discharged. Slidably mounted upon the tube 20 is a piston 21 which when moved downwardly into the container forces the medicinal solution upwardly through the tube 20 as will be readily understood. Upon inspection of Figure 5 it will be noted. that the casting is also provided with a lateral bore or passage 22 communicating with the tube 20, and also with a horizontally disposed tube 23, while the casting is further formed with a laterally disposed bore 24 communicating with the adjacent end of the heatin g device 18, and also with a tube 25 arranged adjacent and parallel with the tube 23. The corresponding outer extremities of the tubes 23 and25 respectively are associated with a mixing device or head 26 in the form of an injector, having a single outlet 27 communicating with bores 28 leading from the respective tubes as illustrated. A vertical bore 29' is also formed in the casting 11, and communicates with the bore 24, to establish communication between the latter and the container '10, so that the aqua solution can be utilized to operate the piston 21 in the manner to be presently described.

The upper end of the tube 20 constitutes a valve seat for the valve 30, and the stem of this valve is threaded into the casting as illustrated and operated by a suitable head or nut 31- The valve, of course, controls the amount of the medicina solution allowed to pass through the tube 20 into the outlet tube 23.

As clearly. illustrated in the drawings, the syringe hereinabove described has associated therewith an electrical heating device indicated generally at 18. which includes a casing of proper cross sectional contour to be fitted within the socket 17. This socket is formed withfa bayonet slot torcceive the 99 pin orllug 34 carried by the heating device. Arranged beneath the casing 18 of the heat ing device. and preferably forming an integral part thereof is a valve body or casing 35 with which the water supply pipe 19 is coupled in any suitable manner. Operating or solution into the heating device. By reawithin the valve body or casing 35 is a valve 86, the stem of whi h indicated at 37 projects out from beyond the body and is formed or provided with a linger enga-gin button 38. Located within the valve body 35 is a spring which normally maintains the valve 86 seateh and rclry cuts of? communication lz-etw en the v... er supply pipe 19 and the heating device 18 through the bore or port l0. A heating elen'ient of any desired construction as it l and arranged rated at ell within the ca 1.9; 18 of the heatmg device, so

that when water is allowed to pass from the supply pipe 19 into the syringe, it passes around the heal'i i cleu'ien :1 and is thereby The (321F111 or body portion ilevice generally is provided 'oal end portion 42 which sw. ch indicated igi'ire 3 the operattca projects from one icion 4-2, and so red with the v: e stem 37, that the entire device can be conveniently handled or manipulated Depending "from He enlarged end 'iortion i a tubular extension 414: which eccivcs Lhe u 1 45 for the heating device- I-ly reason of: the construction illustrated and desk is aa rest that the heating device in us or t be quickly and easily associated with the syringe or removed theretrom the occasion may require. In praconly necessary to adjust or regulate the valve 30, and by holding the device in one and, press upon the valve stem 37, thereby .f .cQfllilliQ' the valve 36 to allow the aqua solution to pass from the supply pipe 19 through the heating device and around the heating element 41. his aqueous solution is also forced through the bore 22 into the tube 25. owever. a portion of the solution is also directed downwardly through the bore 29 into the container 10. thereby depressing the piston 91 and forcing a portion of the medicinal solution upwardly through the tube into the tube The passage of the aqua solution through the tube 25 and the mixing head 26 also creates a su tion in the tube 9.3 to facilitate the discharge of the medicinal solution from the container 10 will be readily appreciated.

The medicinal solution and the aqua solution are brought together and mined in the head 26 before the mixture is discharged from the ejector into the nose, throat other part of the body to be treated. When the device is held in o e hand, the arrangement is such. that the owl ch on be conveniently closed when desired to heat the water flowing through the pipe 19, and at the same time the valve stem 37 can be manipulated by the index finger to regulate the flow of the Water son of the construction illustrated and described it is manifest that a continuous lukewarm or hot sterile medicated spray may be readily obtained when needed, and by simply regulating the valve the flow of the said solution will remain constant until the container 10 is empty.

\Vhile it is believed that from the foregoing description the nature and advantages of the invention will be readily understood, I desire to have it known that I do not limit myself to what is herein illustrated and described and that such changes may be resorted. to when desired as fall within the scope of what is claimed.

What I claim is 1. In a device of the character described. a container for a medicinal solution. a cover therefor a discharge tube depending from the cover into the container, a piston slidably supported on said tube, spaced parallel tubes projecting from said cover, an ejector supported by the outer ends of the last mentioned tubes. one of said tubes having valve controlled communication with the discharge tube, a heating device adapted to be coupled with said cover, a water supply pipe coupled with said heating device, a valve controllii communication between the water supply pipe and said heater, and said cover having a vertical passage for directing portion oi? the water supply against the piston to operate the latter. and an additional bore establishing communication between said heater and the other mentioned parallel. tube for the purpose specified.
